LAMP-BURNER.

Specification of Letters Patent.

Patented Oct. 13, 1908.

To all whom it may concern:

Be it known that I, CHARLES E. WIRTH, a

citizen of the United States, residing at Waterbury, in the county of New Haven and State ofifionnecticut, have invented an Improvement in Lamp-Burners, of which the following is a specification. My invention relates to an oil or fluid font lamp and burner employing an incandescing mantle, and the ob ect of my invention is to increase and make more eflicient the air carrying capacity of the burner and therefore the condition and heat carrying capacity of the flame and illumination or incandesccnce of the mantle. I

In thedevice of my invention the outer wick tubeis made with aflanged ringat the upper end; a foraminous inner deflector surrounding this wick tube is provided with an in'-turned flange at the upper end in the same plane with said flanged ring and slightly spaced apart therefrom so as to leave anannular opening between their juxtaposed edges for an air so ply to the flame. The upper-end ofthis de cot-or is provided with series of circumferentially placed perforations. The lower QIQQJS flat and also provided with -series of perforations 'and' this lower"- end fits within the burner proper.

I provide -a"coi1ical'deflector that is im- It is made with an iii-turned flange at the.upper end which flange comes appreciably above the flange of the inner dellector'. This conical deflector is secured as one with a spring chimney holder of usual construction.

The outeredge of the burner is notched at intervals and the lower peripheral edge of the conical-deflector is made with tongues to pass through these notches sothat upo a partial rotation of the deflector and the chimney holder the same are removably secured to the burner.

Within the central draft tube of the lam are suitable supports for a deflector and the conical deflector member is provided with means by which a standard or bar is secured .and supported and from which the mantle is hung, and I rovide means for indicating the content to w ioh the wick has been raised for use, all ofwhich is hereinafter more partioularly' described.

In the-drawing, Figure 1 is a vertical oentra'lsection through the burner and an olevation of the majorijortion of the mantle flector d. It is and its support. Fig. 2 is a plan of the burner with the conical deflector and spring chimney holder removed. 1g. 3 in larger size is a partial section and elevation of. the upper part of thebiirner showing :the special features of-"iny invention. Fig. 4 is a section in large size througli the parts of the burner where the conical deflector is removably connected to the base of the burner body. Fig. 5 is an elevation of the edge of the burner showing one of the notches. Fig. 6 is an elevation and Fig. 7 a section and partial elevation of the means for determinin the extent to which the wick is raised.

ltefcrring particularly to Fig. 1, a represents the oil font, o the centra draft tube; 1) the burner body of usual perforated con:

struction; b is the wick tube formed therewith and by a screw joint 2 removably con- .tube by the pinion o on the shaft 0 and turned by the disk 0 The upper end of the wick tube l) is exterior-1y provided with a flanged ring 3. I

d represents thefinner deflector made with a cylindrical upper end, a flat base and conical union" witlrla flange 4 in-turned at the upper end. This flange 4 comes closely adjacent in its position to the edge of the flanged ring-'3 and is in the same plane therewith so that between the juxtaposed edges of the two flanges there is an annular opening providin a narrow air passage to the flame. The lower horizontal part of this deflector d is provided-with a series of perforations '5 and at the upper part with a series of perforations =6 and the periphery of the lower part of the deflector-1s preferably turned down as a flange and made to fit snugly within the rim at the up )er end of the burner body I). Notwithstan ing the fact that this inner deflector is of thin metal it is rendered very stiff and rigid by virtue of its construction and because of its peripheral flange and the flan 4.

6 represents a conicalde ector surrounding and spaced apart from the inner dero'vided at its upper end with an in-turne flange e which comes at a" predetermined distance above the flanges 3 4. The opening 'in this flange e agrees substantially with the inner diameter of the wick tube 6.

Withifltlie central draft tube a I have shown ring supports 9 h and a standard 74. connected thereto and upon which is placed a deflector. 'lhis deflector for the lar purposes of my invention and or conthree parts 2' i and F; that is, z is the upper cup shaped part, 2' a center disk and 2* a tubular-body to which the parts 2' and i are connected and which fits over'and is supported by the standard h l represents-the Wick. I have shown upon the pinion shaft 0 sleeves a and o the sleeve a is made fast to the wick tube and passes through the burner body and serves as a bearing, and the sleeve a secured to the shaft 0 by the clamp screw 0 ()n The sleevem and at right angles thereto is a ptiiuter a and a similar pointer 0 on the sleeve 0; the parts 0 o and 0 having an adjustable relation to the partsn n and said parts are .pro-

vided to come into alinement or coincidence.

at such a time as the wick may he raised into the desired position for use. These parts will be adjusted as the wick is burned down and trimmed. v

The burner body 6' is provided with equidistantspaced apart notches S in its peripheijv. i see 2, a and 5) and the lower portion of the conical deflector is provided with tongues J and when the parts are broughttogether, the tongues 9 pass through the notches 8 in bringing the conical deflector down upon the upper edge of the burner. The conical deflector is then given a slight turn so as to bring'the tongues beneath its full periphery so as'to clamp said parts together.

The es .tial object of my invention is to increase i make more ciiicuent the air carrying ca aty of the burner and. to even supply totlic burner more air to produce the usual light giving flame. This will tend to heat and vaporize the fluid at the u per end of the Wick and to cause a flame o burning vapor more than a flame of burning fluid, and the same as effected in the construction shown and described, tends to force the name outward against the manthan is needed and in the-operation ofthe I device of my improvenient and with special reference to Fig.
